When a text bears this symbol, damage to equipment or poor efficiency may be the consequence of not following the instructions. CAUTION! When a text bears this symbol, it means that personal injury or serious damage to the equipment may result if the instructions are not followed. ! Symbols used These products have a number of symbols that are used to label the product itself and in the installation and user documentation. Supply air Extract air DANGER! ELECTRICITY Kitchen air DANGER! DO NOT TOUCH Exhaust air Outdoor air 4 2 Functional description of balanced ventilation 2.1 Fans (M1, M2) 2.4 The fans ensure that air enters and leaves the building. They can be individually adjusted for optimal operation. The unit can be regulated at three different speeds via the control panel: Min, Normal and Max. 2.2 If the energy recovered from the extract air is insufficient to maintain the set supply air temperature, an electric heating element will help raise the temperature. The heating element is protected against overheating by the thermostat (F20) which cuts out at high temperature. For extra safety, the thermostat (F10) cuts out at critical temperatures. (The F10 thermostat must be reset manually by pressing the reset button.) Filters (FI1, FI2) Filters with a high filter grade (F7) are used as standard for both supply air and extract air, so that the air which enters the building is clean. The filters also ensure that the unit stays clean and can maintain thermal efficiency and air flow. 2.3 2.5 Temperature sensors (B1, B4) As standard, the unit has two temperature sensors. Supply air sensor (B1) records the temperature after the heating battery. Outdoor air sensor (B4) registers the temperature of the outdoor air. Rotor (HR-R) The air passes through the rotary heat exchanger (recovery system). The rotor functions as a heat magazine. The heat from the extract air heats up one part of the rotor. When the heated part comes over to the supply air side, the heat is transferred to the supply air. ! Heating element (EB1) Adjustment must always be carried out by qualified personnel before the installation is used for the first time.

The control unit communicates with the ventilation unit via a low-voltage cable. 5.2 The temperature required for the supply air can be set with knob 11. The adjustment range is 10-30°C. Use of the factory settings is recommended. If necessary, the ventilation unit's heating can also be switched ON/OFF with switch 10. In this case only the rotating heat exchanger is used as a source of heat. It is best to leave it in ON position, as the unit will then respond automatically when there is a need for additional heating. Increasing/reducing the air supply Use switches 1 and 2 to increase and reduce the fan speed and with it the air flow rate. The following speeds are used depending on the operating situation. MIN Adjusting the temperature Must not be used when the home is in use. Must not be used in the first year of operation. Item 10 ON OFF NORMAL Used under normal conditions. On this setting the air supply must be adjusted according to current regulations. MAX Used if there is a need for increased air supply on account of higher occupancy or a raised humidity level, for example during showering or when clothes are being dried. This setting is normally used for limited periods. 5.5 LED 7, which is yellow, lights up every six months as a reminder that it is time to change the air filters in the unit. See 10.1 Changing the filters for more information on changing filters. The different speeds are indicated by LEDs 3, 4 and 5. 5.3 Once the activity has been carried out, the indicator must be reset. See more under the section on resetting. Adjusting the air supply At NORMAL speed level, the air flow must be adjusted according to project data. Potentiometer 9 is used for the supply air level and potentiometer 8 for the extract air level. The adjustment range is 20-100% of the maximum level according to the scale of the potentiometer. 5.6 50% (fixed) NORMAL 75% (variable) MAX 100% (fixed) 9 10 Alarm If anything unforeseen occurs with the ventilation unit, indicator 6 will light up. The indicator signal will depend on the reason for it coming on. Factory settings: MIN Changing the filters ! A steady light indicates: • Error on return water sensor (B5) • Error on heat recovery (B alarm) Steady light with flashing MIN speed (indicator 5) indicates: • Error on supply air sensor (B1) • Error on extract air sensor (B3) • Error on outdoor air sensor (B4) 8 A flashing light indicates: • Overheating thermostat fault (applies only to electric heating) • Fault in external fire/smoke detector (accessory) • Error on heat recovery (A alarm) • Error on water battery (applies only to electric heating) 11 8 5.7 Resetting NB! If thermostat F10 trips, the unit will have to be opened up and physically reset before resetting on the panel. If the alarm trips repeatedly, contact the service company or distributor. Once the filter has been changed or the cause of the alarm rectified, the alarm must be reset. This is done by pressing switch 12. If the indicator goes out, the action has been carried out correctly. If the indicator remains on, the fault has not been rectified correctly. 6 Overview of CI600 control panel 6 1* 7 2 8 3 9 No. Description 1* UP/INCREASE switch 2 BACK/CANCEL/NO switch 3 DOWN/DECREASE switch 4 OK/YES switch 5 HELP switch 6 Display 7 Indication for OPERATION/OK -Green light 8 Indication for FILTER CHANGE -Yellow light 9 Indication for ALARM -Red light 4 *The numbers are used as references in subsequent descriptions 9 5 7 CI600 in use 7.1 General If you select a function that has numerical values, the current value is displayed with a light blue cursor.

In general, the filters need to be changed at least once a year, preferably in the autumn (after the pollen season). In areas with a lot of dust and pollution, the filters should be changed in the spring and autumn. figur 2 Changing the filters Check that the seal is intact before inserting the filter. Then push the filter drawer fully into place to prevent air leakage. Dirty filters can, among other things, lead to: • Reduced performance of the unit • The unit becoming dirty • Humidity damage in the home • Reduced indoor air quality Make sure that the filter is not damaged during fitting. Use the filter's outer edge to push it in. A damaged filter reduces the output of the unit and the purity of the air. A filter subscription is recommended to ensure full benefit from the system. Both filters should always be changed. To take out the filters: 1. Pull the filter drawer out as far as it will go. The drawer does not have to be removed completely. 2. The filter is now loose and can be removed. 3. Put a new filter in and push the drawer fully into place. When changing the filter, check that the whole unit is working normally. Use the following checklist: • Check that the rotor is rotating. Turn the rotor in the direction of rotation as shown on the rotor cassette. • If necessary, clean the rotor. • Check that the fans are clean. figur 3 Rotational direction of rotor 19 10.2 Cleaning the fans The fans must be cleaned at least once a year. Clean the fan blades with a grease solvent on a cloth (e.g. methylated spirits) and compressed air if possible. NB Take care that the motor is not exposed to water. To take out the fans: 1. Undo the screws on the electric cover and take the cover off. 2. Release both fan contacts 3. Release the wires to the fans, take the cable bushings along with you. 4. a) Extract the fan brackets (two per fan) ! Note that the fans will fall out when the fan brackets are released. b) Extract the fans, being careful not to damage the cable. To put the fans back, follow the points in reverse order. 3 2 3 1 a b 4 20 10.3 Changing the brush strips The brush strips become worn over time. If they do not lie tightly against the rotary exchanger, it may be necessary to change them. Alternatively, they may be moved closer to the rotor, as the aluminium profile they are mounted in has two grooves. Proceed as follows: 1. 2. 3. Undo the screws on the electric cover and take the cover off. Draw out the electrical board Disconnect the rotor's quick-release contact from the circuit board by pressing the release down and pulling the contact. ! 4. 5. Note that the fans will fall out when the fan brackets are released. Undo the screws on the electric cover and take the cover off. Pull the rotor module straight out. 4 5 2 1 3 continued next page 21 6. Flip off the brush strip profiles with a screwdriver, etc. There are 4 brush strips on the rotor, 2 on each side. 6 Use a large screwdriver, so you can get a good contact without bending the profile. Start at one end and continue to the other. 7. 8. Pull the brush strips out of the groove. Move the brush strips down to level 2), or replace them with new ones if they are completely worn out. 7 8 LEVEL 1 LEVEL 2 10.4 Cleaning the rotor High impermeability filters are installed in the unit. It is not therefore usually necessary to clean the rotor. If, for various reasons, it should still be necessary, dust can be removed with a soft brush. Further cleaning is possible by removing the rotor, spraying it with a grease solvent and then blowing it clean from the opposite side. Distance approximately 60 mm and max. pressure 8 bar. Ensure that the motor is not exposed to water during cleaning. Ensure that all seals around the rotor are intact and tight. Ensure that there is no damage to the rotor belt, and that the rotor rotates freely. Do not use abrasive cleaners or scouring powder, as such products can damage the surfaces. Cleaners containing ammonia or citrus must not be used. Products that give stainless steel an anti-fingerprint coating must not be used either. 10.5 External cleaning Many kitchen surface cleaners contain chemicals that may damage the product’s plastic components. Therefore use a soft cloth moistened with warm water and a neutral detergent to clean the outside of the product. 22 11 Maintenance table Component Action Interval Filter Filters must be changed at least once a year.
